Hello all CERBIOS will try and boot from a CD if there is one inserted at boot. This means if it’s a game or music CD then nothing happens! i want to change the bios but I am unsure of what line of text I am supposed to change? firstly I am very impressed with the new CERBIOS update. if you are having any problems currently please update to the latest… I am not very technically minded. When I updated the bios I had to use the actual NEW file that came with the V2.2.0 zip and change the boot directory! It wouldn’t except me just copying the text to the old one! I have a dual bank modchip so on the CERBIOS bank I would like to change the bios file to “NOT TRY TO BOOT FROM CD IF PRESENT” . I am happy to do the button combination at boot using IND_BIOs if I ever wanted to use a HEXEN disk. please can you assist

Hey all, tl;dr Started to recap my 1.4, testing as I went. Board eventually started to 3 boot frag, cannot get it to recover. Did I break it beyond repair? So, I replaced the power supply that I accidentally blew up and all was good. Since I noticed that the caps by the CPU were bulging, I figured I might as well replace them before going any further so I ordered a full board cap kit from Console5. I've recapped other devices before, but I guess I must have been lucky because this gave me problems immediately. The multi-layer board and large ground planes made it extremely difficult to get caps out and clear the vias of left over solder. I don't have a hot air station or board pre-heater or anything like that which I'm sure would have made things much easier (one bedroom apartment with two people and a cat, space is at a premium). Since I was afraid I was doing damage to pads/internal board layers getting caps and solder out, I made sure to test the system after replacing every few caps. I decided not to do the whole board since I was having difficulty, and would stop after these last few. Well, after replacing those last few the system no longer boots. Here's what I'm getting: The first few times I tried booting, I got the 3 boots and FRAG. I reflowed some solder on questionable joints and got a solid green light, but no AV (seems to indicate inability to load a BIOS). Unplugged my modchip, but same issue. While not impossible, it seemed unlikely that both the onboard BIOS (this board was previously TSOPed) and the modchip BIOS would be corrupted so I felt I must have done too much board damage somewhere and maybe destroyed an internal trace or something. After going back and forth checking all the caps I replaced and even trying to solder from the top side to ensure a through-and-through connection (please, forgive me), I wound up at: 3 boot FRAG when modchip installed, but solid green no AV with modchip uninstalled. This led me to think that maybe there was an issue with the LPC though I hadn't touched that area since I originally installed the pin header 4 years ago. I reflowed those joints and moved the D0 wire from the Aladdin chip to a ground/screw hole on the board. Continuity between LPC pins and their respective traces check out fine on my multi meter. Now I get 3 boot frag with or without the modchip plugged in. Anyone have any advice or see anything in the pictures that I don't? Any help is appreciated. Pictures: https://imgur.com/a/WEKo0vb The caps circled in blue at the ones I replaced and was able to still boot after. The ones in red are the last ones I replaced, no booting since replacing them. All other caps are original.

Hello, I'm new here. I'm from Italy so my english couldn't be perfect, forgive me A friend of mine gave me an Xbox ver. 1.6, he wants me to try to fix that after he careless removed the Aladdin modchip. In other words, he removed it without using a soldering iron; the modchip was directly soldered to LPC holes. He also removed the LPC rebuild. I've got the original HDD still working, so I'd like to bring it back without installing a new modchip. My friend himself would want it alive as a stock Xbox. Here's the link with some pics I've taken: https://imgur.com/a/Fk3W0pI Any suggestions are accepted. Thanks in advance. Max

Hi All, Today I just finished upgrading my 1.4 board with an X3 as the chip to 128mb of ram. The upgrade went great no issues with a hot air rework station. I flashed Xblast OS to one of the banks of the X3 and tested each chip as it was installed, I got a"success" on all 4 chips. Put the board back in and hooked it up, booted into X3 Config Live and the X3 recognizes 128mb of ram. Switched banks to the latest Cerbios release (2.4.1) and the box just hangs at the Cerbios Logo (not the dogs, I know about the issue). Any suggestions on this situation? I tried the 2.3.1 and got the same thing. I tried booting into Cerbios Safe mode with eject and got a black screen (no logo). I tried 2.3.1 udma 2-5. No luck Thanks for your replies, Zagman

OGXBox Boot Menu Just a simple boot menu which offers the function to not just launch your DVD or Dash, you can also set one dash as default if you wish. Ofc FTP is also available set to DHCP (you can change that in the settings). XBlast can be launched from the Misc menu as well as the File Explorer. It may come handy for the one or the other. If you sell pre modded xboxes it can be useful to let the buyer decide what he wants. How ever, here is the DL folder (maybe for updates but it should be bug free), a video which shows the options, and a simple screen shot. Peace.

After I power up the console and it goes thru the start sequence it just takes longer than it should, compared to my other consoles. Probably twice as long. Other than that, once booted it works fine. Any ideas?

Hello everyone, I have a !.0 MOBO that I have recently installed Project stellar on along with the HD+ kit from MakeMhz. I had the ribbon cable to the video encoder professionally soldered on but the rest of the install I was able to complete myself. once i reassembled the unit I was able to get it to post with only the mod chip with no DVD or HDD drive but I had no audio only the splash screen. I then completely reassembled to see if it was an issue with no hard drive (shouldn't be i thought to myself) so unsurprisingly it still had no audio (but the picture is OUTSTANDING). anyway I took everything apart to check my work and now seem to have narrowed down the sound issue to hopefully a bad wire included in the kit or a setting issue on the MS DASH feel free to let me know your thoughts on the audio issue as well. BUT when going to try the MS DASH first i reassembled and now the mod chip itself (project stellar) wont boot idk if the xbox is bricked now or what, I seem to get power to the chip as seen by the little green indicator light on the bottom of the chip but the tiny screen does not display anything not even an error code. So I reconnected the chip to my PC and found that the screen itself does in fact work it displays "PC Mode" so I know the screen didn't die and all of the firmware and bios seem to be on the chip and website tells me that the chip is ready for install now. I figure I should get the chip working first before I can do anymore diagnosing on this thing. At this point I am lost. I'm just trying to make a good birthday present for my little brother. please any help is appreciated TIA!

Hi, all I have modded a xbox with an flashable aladin modchip, every thing was fine, flash cerbios, the install xmbc for gamers, give back the xbox to the owner, he was happy. He notice after a few weeks that he got like some wave in the screen, so I search to find that could be from bad caps so he take me back is xbox to check it out. I take it appart to check if I see bad caps and I see nothing, I put back together the xbox and now it's booting and stuck on cerbios screen and when I try to boot with eject it's stuck on cerbios safe mode screen. What could do that and what I could do to resolve this problem ?

I love this skin, so. there's a way to edit xml to xbox boot directly into GAMES tab, i mean, i rarely use any of the other tabs...

I have 2 XBOXes v1.2 and v1.6 with Rocky5 softmod v1.1.6. I was messing around with the NKPatcher and nulled the HDD drive key on one of them before backing up the EEPROM and now it boots up to error 05. It seems I need to format it using the hotswap method, xboxhdm v1.9 and a backup of the Dashboard from the C partition, which I don't have. Can I use the files from the other XBOX? EDIT: I'm probably looking at it fro the wrong angle... when using the hotswap, won't I get access to the backed up EEPROM in the E partition? Can it be used to restore the HDD?Or is it better to just format it and start from scratch? This subject is still pretty new to me.

Evening, guys, Having Aladdin XT modchip with ind-bios, I wish I could use xbmc4gamer or emustation as a dashboard at boot. I tried to look for a guide to talk about it to a Moon like me but without success. That's the way my partitions are: C Microsoft Dash F Dash no boot (Evolution, xbmc4gamer). Who can tell me the right guide? Thanks to everyone as always.

Hey all. I am needed some help here. Box will boot fine sometimes, and other times, I get no video or audio. Weird part is I get no FRAG. Lights on the box are normal for the boot sequence. All green, no flashing colors. I have a 1.2/1.3 that I TSOP'd and installed the additional 64mb of RAM. RAM all checks out in xblast and in XBMC and clock cap was pulled. Other caps look fine, but replacements are on order. 4tb WD Blue and Startech with 80wire IDE. Just don't know what would be giving me inconsistent boots at this time.

Thanks to SS_Dave I put the OEM dash file on the Xbox to try and boot to there from UnleashX. However when I try to run it I get Error 21. I think it got messed up by whoever soft modded the console before I bought it (it had been sitting in that shop for a few years), but even then I did a clean UnleashX install with Rocky5's tool. I'm pretty confused on what to do. Will I need to put in Halo 2 or something with XBL to update the OEM dash, and then reinstall UnleashX using the Splinter Cell exploit?

Hi all, ive been using the chinese style adapters from ebay but the price has been creeping up on them so thought i would source a bulk from alibaba, they looked the same on the pics so thought i would be good to go, i ordered 10. they work but the console takes ages to go from the xbox splash screen (without the microsoft tag) to the little microsoft tag appearing at the bottom (15 - 20 seconds as opposed to 1 or 2 seconds with the other adapters), once that has appeared they work fine, everything else is the same speedwise. looking at these adapters they actually look better quality, even the master/slave jumper comes in its own little bag, one other thing I've noticed is they work with the standard 40 pin ide cable whereas the other chinese adapters only worked with an 80 pin. anyone had any experience of these?

Hey guys. So I'm working on a softmod and I wanted to try the dual boot with different dashes, and controlling the boots with eject and power. Any help would be much appreciated.

HI I just got a new xbox with smartxx v1 or v2 bot sadly it does not wanna boot into smartxx os/ does it hava a os like the opx? can I reflash it to get it back than? Eject and power does boot into evox Gruß

When pressing the power button, nothing happens. Sometimes it would make the fan reach max speed 3 times and flash orange for a split second. Sometimes it would do something in between and slightly nudge the fan to spin and nothing more. I should mention my xbox has a modchip. Based off the information i have gathered from forums and reddit posts, this is what i know; - IDE cable and disc drive are not the cause of the problem, everything is disconnected from the motherboard - power button and eject button work - checked the board for corrosion, cleaned with iso. alchohol - fuse on power supply is good - checked voltages on power supply ATX connector (connected it to the motherboard, stuck the probes inside the connector where the wires go and pressed the power button. This probably isnt the way to do it i know). The standby and power on voltages match, but after a few seconds the drop back to zero (excluding the orange wires which do have standby voltage) because i presume the xbox doesnt boot - checked the transistor at Q7C2 and i am not getting a match for the voltages. 1.1v on the collector and 0.6 on the emitter. I might have read the values wrong, but the still dont reach what the are supposed to Not losing hope, open to all suggestions

So separate to my Softmod in another thread, I also have an old Xecuter 2.3b lite which has sat in my toolbox for about 15 years or so. Physically it's in pristine condition. I have no idea what bios it should/might have on it, as it was removed from my old Xbox way back when after I got another (original Xenium) chip. I have the ground/D0 cable and a switch module. I'm not the worlds best solderer but I managed to use braid etc to remove the solder from the LPC holes on my v1.0 board, and solder in a 12 pin header. I don't have the cable for the switch module for this chip, so have tried using spare wire to set the switches so the chip would be enabled. The LED's on the chip light up when powered on, regardless of the state of ground/D0. However, if I jumper the pins to enable the chip, or ground D0, my console frags (eg on/off three times, ending with flashing green/red light). I have triple checked my soldering. I used a multimeter to test all the pins on the LPC following a guide in another thread and voltages etc appear correct when the console is powered on. D0 is definitely correct as there is continuity if I bridge the top D0 point with the wire (which is soldered to the bottom D0 point). My question is, if the Modchip bios isn't correctly flashed/loaded, would that cause a Frag? I'm worried my soldering isn't good enough but all the multimeter tests seem to indicate everything is working as it should be, leading me to think the chip is faulty/dead (even though the LED's light). I'm close to ordering an OpenXenium if I can find one somewhere, as that will negate my TSOP/HDD issues, but just worried there might be something i'm missing with my soldering etc. Thanks for any advice

(Cross-posting from Reddit having done further testing to see if anyone has any other ideas on how to fix this) My hard-modded Xbox 1.2 with OpenXenium and Cerbios 2.3.2 Alpha set as the default BIOS has an issue where it'll take several attempts to boot fully into XBMC4Gamers. If I power the machine on, the power, eject button and controller port lights come on, the DVD drive clicks a couple of times and the disk activity light stays solidly on for 5-10 seconds before stopping. The machine will then get stuck on a black screen and I have to power cycle it. I've noticed that the Xbox seems less likely to boot successfully if I boot it up 'cold' for the first time in several days or weeks whereas it's more likely to boot if I try it 4 or 5 times in quick succession. The machine has the following: XboxHD+ Revision 3C (the issue still occurred when I was using a component cable instead of HDMI) iND-BiOS, EvoX M8 Plus 1.0.5838.1 and Cerbios 2.3.2 Alpha added via the OpenXenium launch menu - the issue occurs with all 3 BIOSes Crucial MX500 2TB SSD connected via a StarTech IDE to SATA adaptor Brook Wingman XB2 paired wirelessly with official Xbox Series X controller - I've noticed when using Cerbios that the controller pairs successfully even when the machine gets stuck on a black screen? replacement capacitors clock capacitor removed DVD drive belt replaced 128MB RAM upgrade I bought the Xbox pre-modded on eBay and the last 3 items on that list were done by the seller. Other hardware mods like the XboxHD+ installation and replacement capacitors were done by the trusted UK modder I use. I've tried rebuilding the C:\ drive using an OG Xbox Installer 2021 DVD (or at least manually doing the equivalent using the built-in file manager as some of the files were failing to read off the drive) but that didn't make a difference. Once the machine has booted fully, it seems pretty stable and I've been able to complete several games on the system. Any ideas what can be done to get the machine to boot more reliably? If it's a hardware issue, I don't have any soldering skills but I don't mind sending it off to get it looked at - I'm just hoping that the issue is fixable as I don't really want the hassle of purchasing a replacement console and having to transplant everything over.

Howdy! Long time follower of the forums and this is my first post ever on the site. Finally got me a modded original NTSC Xbox from eBay after years of not owning one. Loving it! Mostly playing Halo2 on XLinkKai. My only issue with it is that who ever modded it and sold it to me on eBay removed the iconic classic flubber intro boot, all it has is just this blame and dull blue Xbox logo during boot and nothing else. Looking to see if there is anyway I can get the flubber screen back? I know it's something to do with the BIOS, just haven't found any leads in what to do and all the information i used to frequent back in the day on isozone is gone and anything I find is obscure with no clear information or instructions and I'm afraid to mess anything up with out some kind guidance on the procedure. I'd really appreciate the help or any kind lead. Thanks in advance!

Howdy! Long time follower of the forums and well this is my first post ever on the site. Finally got me a modded original NTSC Xbox from eBay after years of not owning one. Loving it!

I mean it's cool and I guess, but anyway I can get the flubber screen back? Kind of a sucker for the nostalgia, also figure this would be an excellent way to find my way around the machine and get familiar w the different types of software and methods. I know it's something to do with the BIOS, just haven't found any leads in what to do and all the information i used to frequent back in the day is gone or anything I find is obscure with no instructions and I'm afraid to mess anything up with out guidance. I'd really appreciate the help or any kind leads for this little "project". Thanks in advance! Keep the OG Xbox scene alive

I'm messing around with my own Xbox OG and have a modchip with Cerbios in it. I also changed the default hard drive with a SATA 160GB version and an IDE2SATA adapter with 80 wires 40 pins IDE cable. The boot is slow and yes I know the cheap IDE2SATA adapters can be annoying. But I used the exact same adapter in other Xboxes and they work fine. So, I did some testing. With the DVD drive attached (in the cerbios.ini it is defined as DriveSetup = 1 (which is HDD & No DVD (Legacy Mode)) the boot time is 42 seconds. When I detach the DVD drive, the boot time is aprox 20 to 21 seconds before the full EvolutionX dash is loaded. I tried several DVD drives (the one original in this Xbox is a Thompson, but I also tried Philips, Samsung) and the load time is with the DVD drive attached always 42 seconds and without at max 21 seconds. I also tried another 80 wires 40 pins IDE cable a had laying around, but same issue. Because I sometimes use the DVD drive I can`t eliminate it, so I'm out of ideas. If the adapter was also slow without the DVD, I would suspect that to be the problem, but in this case the performance without the DVD is fine (I also tested the adapter in a PC and it has good throughput). So if anyone has an idea to check and improve the time with the DVD attached it would be nice.

OK, new modder confused here. I've been spending my time fixing up dead and half dead boxes, and thought I'd see how setting up a new hard drive works with a hardmodded console. I used the OG Xbox Install disc to TSOP to Evox m8+ nodvd, wiped the stock HDD and installed UnleashX and the default apps, and it boots fine. However, now when I swap a different drive to set up (either a 10GB drive from another Xbox, or a WD 80GB drive) the box fails to boot from DVD. I've tried with two different DVD drives, but it's always the same... even the seeking sound the optical drives make are the same (they keep going forever in an identical repeating "pattern" until I switch the console off - no, not impatient, waited for 5-10 minutes). When I switch back to the original HDD, the system boots up fine from it, and also boots from the DVD drive - and the DVD drive sounds "healthy" again compared to previous attempts. I tried powering the bigger new HDD with an external power supply, since I noticed it was pulling more power on the 12V rail (thinking maybe the old PSU is just at its end), but this makes no difference. I've also tried jumpering the drive to cable select and master+slave, but still nothing. The original drive is a Seagate, both replacements were WD. Is there something I've overlooked?

I have an Xbox with an Xecuter 3, X3CP, and the daughterboards for the controller port and front panel PCB, booting from the chip requires pressing the eject button but I have a couple of problems with this: - Booting with the eject button causes Cerbios to boot into safemode and not display any boot animation - Opening the disc tray each start up puts unnecessary wear on it, that's something I'd like to avoid I hardly have any experience with the X3, is there a way to enable the chip no matter what button powers the console on, or a way to switch which button enables it? I'd prefer to keep the ability to boot to the backup image

Hi all, just finished a cerbios build for a friend. It’s a 1.2 with a 4TB drive. I’m finding that every so often the system will freeze. When I reboot the system, I’ll just have a black screen or sometimes black screen with a sporadic blink of an image onscreen. Then I’ll get a quick green flash on the eject light. Does anyone know what a flashing green light might mean?
